The Coffee club at London University launched their coffee shop Thoughts few months ago. Thoughts have the following expenses:

Rental $80 per day

Coffee beans $5 per Coffee Cup

Sugar $0.3 per Coffee Cup

Flavors $ 0.5 per Coffee Cup

Filtered water $0.2 per Coffee Cup

Labor $30 per day

a-Calculate the fixed cost and the variable cost per day

b-If 30 students per day visit the coffee shop (each student buys one cup of coffee), how much the Manager should charge per Coffee Cup in order to breakeven?

c-After conducting a Market Survey, the Manager found out that he can charge up to $8 per Coffee Cup and decided to do so. How many students should visit Thoughts so it doesn't operate at a loss?
